One of the outstanding differences between these key periods of Western Classical Music is the change in creative thinking. Baroque music as we can clearly hear in the music of a composer such as J. S Bach is textural complexity and the dominance of polyphonic writing. The Classical period moved dramatically away from this dense, intricate compositional style towards clear a melodic line and accompaniment; or homophony. This doesn’t mean that Mozart or Haydn for example, abandoned the earlier musical forms and fugue features in both of these composers works, particularly the String Quartets.
